Abstract

A ceramic matrix composite (CMC) component segment (210, 212; 310) forming a portion of a substantially ring-shaped gas turbine engine stage includes a mateface (230, 232) extending axially between an upstream end and a downstream end of the CMC component (210) and configured to form an inter-segment gap (250) with an adjacent CMC component (212), and a plurality of film cooling holes (234) having diffused openings at the mateface (230, 232) to provide film cooling of the mateface (230, 232). A method of providing an inter-segment purge flow to such a CMC component (210, 212) includes disposing a first mateface (230) of the CMC component segment (210) next to a second mateface (232) of an adjacent CMC component segment (212) to form an inter-segment gap (250), and providing first film cooling of the first mateface (230) via the plurality of film cooling holes (234) having diffused openings at the first mateface (230).
